BUTTER-TUB covert.

Application filed February 14, 1927.

The invention relates to covers for butter tubs and the like and more particularly to a novel retaining band therefor.

It has been the general practice to provide a butter tub cover witha straight walled rim or retaining band of uniform width, which band was attached to the cover plate by means of suitable fastening devices, such as nails, driven through the band at frequent intervals and into the cover plate. The upper edge of the band was positioned adjacent the top surface of the cover plate, the lower portion of t 1e band depending below the plate to surround the upper portion of the tub to retain the cover thereon.

This construction entailed numerous disadvantages and inconveniences. For example, it required considerable labor to nail the band to the cover plate, and when so secured, some portion of the upper edge of the band generally extended above the plate so as to make it difficult to slide one covered tub upon another, such as is desirable during the transportation thereof, and also the nail heads were liable to catch and injure thehands of those handling the tubs. Furthermore the band usually depended straight downwardly from the edge of the cover and rendered it impossible to nest the covers one upon the other when stored or transported separately from the tubs.

It is an object of the invention to provide an improved cover of simple, inexpensive and efficient construction which obviates such disadvantageous features of former constructions.

It is another object of the invention to provide a cover having a peripheral groove in the edge thereof, and a retaining band with a bead formed thereon, corresponding with and seating in said groove, so as accurately to position the band on the peripheral edge of the cover and to permit the band to be retained securely thereon by one or two nails driven through the ends of the band.

Further objects and advantages of the invention will become apparent as the description proceeds.

In the drawings:

Figure 1 is a plan view of a: cover embodying the invention in its preferred form.

Fig. 2 is a fragmental side elevation thereof.

Fig. 3 is a fragmentary radial section of Serial No. 167,895.

the cover of Figs. 1 and 2 positioned on a receptacle.

For purposes of disclosure, I have illustrated in the drawings and will hereinafter describe in detail the preferred embodiment of the invention, with the understanding that I do not intend to limitthe invention to the particular construction and arrangement shown, it being contemplated that various changes may be made by those skilled in the art without departing from the spirit and scope of the appended claim.

In the form chosen for purposes of disclosure, the invention is illustrated as embodied in a. wooden cover 1 for a butter tub or other receptacle having a side wall 2. The cover 1 may be circular to conform with the general practice and comprises a cover plate or disk 3, and a retaining band 4 secured thereto about its edge for the purpose of retaining the cover in place on the tub.

For the purpose of positioning the band on the edge of the cover plate, the plate is pro vided with a groove 5 extending around the peripheral edge thereof and the band 4: is formed with an inwardly extending flange or head 6 adapted to be driven into the groove 5 with the opposite ends 7, 8 of the band overla ping. Thus, the band may be positioned readily and accurately upon the cover plate,

merely by inserting the bead 6 on the band in the groove in the plate, so that the upper edge of the band will not project above the top of the plate. The band may then be effectively secured to the plate by means of nails 9 driven through the bead of the overlapped port-ions of the band and into the plate. The heads of the nails are preferably driven into the outward side of the bead and thereby countersunk so as not to extend beyond the peripheral surface of the cover.

The depending or retaining portion 10 of the band is illustrated as being offset or flared outwardly from the upper portion of the band so as to permit a plurality of duplicate covers to be nested one upon another, with the cover plates abutting and within the flared portion of the band of the adjacent cover. At its lower edge the band may be reenforced by means of a head 11.

It will be apparent from the foregoing that in the preferred form illustrated, the invention provides a simple and efiiciently constructed cover. The retaining band may be readily positioned accurately upon the edge of the cover plate and may be effectively secured {thereto by one ortwo nails driven through the ends of the band and vinto the disk from the same general direction. lVith the heads of the nails countersunk in the hand, a slight flare of the lower portion of the band permits of the covers being nested Thus the invention in addition to providing a simple and eilicient construction permits of convenient handling and transportation, both oi the'co'vers separately from the tube or of tubs with covers secured in place thereon.

I claim as my invention:

A cover comprising aplate adapted to be positioned in endv'ard abutment With thesidc Wall of a tub to-eliect the closure of said tub and having acontinnous groove formed in its peripheral edge, a band pos tioned about the edge oi said plate and having ahead formed therein extending into said groove, said band eover these-upon, and a headed device driven through said head into the edge of said plate to secure said band thereto, said device having' its, head positioned within said head and said groove inwardly of the adjacent outer smrl'ace 0:5 said band.

In testimony whereof, I have hereunto atfixed my signature.
